ORBIT-USER: RSSI report in Intel card

[Sangho Oh]

Anybody familiar with Intel cards?
I am trying to log the RSSIs from the received packets, but there in 
information in the header (such as prism in Atheros) in the packet.

I configured the cards
- iwconfig eth2 mode monitor
- iwconfig eth2 channel 44
- iwconfig eth2 essid mybssid

and logged with tcpdump using libpcap.

Thanks in advance.
